6150299f54 Merged in masayuki2009/nuttx.nuttx/irq_spinlock (pull request #550) 
SMP: Introduce spin_lock_irqsave() and spin_unlock_irqrestore()

These APIs are simplified version of enter_critical_section() and
leave_critical_section() to protect data (e.g. registers) in SMP mode.
By using these APIs inside drivers, performace will be improved.

8eaa587c98 sched: move POSIX thread specific data from pthread TCB to common TCB structure. This change allows using pthread_getspecific/pthread_setspecific from main thread. Patch also enables using pthread data with config option CONFIG_DISABLE_PTHREAD=y. 2017-10-25 07:06:42 -06:00

42a0796615 Squashed commit of the following: 
sched/semaphore:  Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable.  Changed all references to sem_post in the OS to nxsem_post().

    sched/semaphore:  Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable.  Changed all references to sem_destroy() in the OS to nxsem_destroy().

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS
